The AROS distribution Icaros Desktop has made its next step towards compatibility with legacy Amiga workbench applications, including an entire AROS enviroment compiled for the classic Amiga platform, which is almost binary compatible with the original Amiga OS 3.1 (and its extensions). When the user needs an old program, he or she only has to fire up the AROS M68K environment and run the application. The Amiga virtual machine can optionally be set to run at startup like a system service.

>integrating Amiga Forever from Cloanto into Icaros installations has been the only way to get a perfect compatibility with older AmigaOS applications

You don't need Amiga Forever nor AROS for this.
AROS is still missing large chunks of functionality. Eg. the standard GUI since 1999 is ReAction, this is not supported at all by AROS, neither are OS3.5/3.9 API calls.
WinUAE+OS3.9 still provides the best compatibility. I'm not sure why anyone would want to run AROS instead.

Somehow the UAE version with "Win" is the one furthest along ...and a source of its similarly mature forks for other platforms; probably why "WinUAE" not "UAE" is a fairly common description.

But let me guess, you also avoid AROS at all due to x86 part (or Amithlon in the past - the fastest Amiga back then, probably still if it was kept alive, and offering a smooth migration - IIRC, x86 apps and libs could run along the 68k ones; yeah, there were legal issues, but likewise with OS4).
Hell... why do you call present Amiga computers "Amiga"? They are basically PCs, just with uncommon CPUs for no good reason. And most of present software making them semi-useful are ports of PC stuff.

Somehow you've comploetely missed the entire point of AROS. AROS was never intended to be another way to emulate Amiga 68K software. AROS is a reimplementatin of Amiga OS 3.1 on modern hardware with new extensions that allow AROS users to have all the things they'd expect from a modern system, such as 3D hardware acceleration using Gallium3D.. The article was just stating that if you want to emulate Amiga 68K software under AROS, it's now seamless. Stop trolling.

Standard, de facto GUI for Amiga OSes has ever been MUI. The ReAction path has been followed and endorsed by Hyperion, but most applications - even "NG" ones - use MUI and can be supported by AROS' Zune MUI clone.

Good point, MUI has been king since the 90s. Does this count for OS 4.x apps as well though? I was under the impression MUI was now a MorphOS/AROS(Zune) thing and that OS 4 didn´t get support?

Might be totally off the mark though, as I only keep an eye on AROS of the NG platforms nowadays.
